TUBE88 — A code which computes magnetic field lines

Abstract TUBE88 computes magnetic field lines in cylindrical or toroidal geometry (using cylindrical coordinates (r, φ, z)) and calculates the intersections of those field lines with specified planes. It is an outgrowth of a code first written in 1967. A fourth-order predictor-corrector method is used to integrate the field line coordinates. The magnetic field may be computed in several ways: (a) through specification of currents flowing in very specific helical and circular elements together with a “...
